Title:
WATER TREATMENT SYSTEM AND WATER TREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2020/241382
Kind Code:
A1
Abstract:
The present invention provides a water treatment system with which it is possible to estimate the amount of microorganisms adhering to a flat plate on the basis of information from a contactless sensor and to autonomously control a water treatment operation on the basis of the result of estimation. According to an embodiment, there is provided a water treatment system that purifies raw water through use of microorganisms while causing a flat plate to which the microorganisms adhere to rotate so that a part of the flat plate is immersed in the raw water, the water treatment system being provided with a controller that controls the operation of the water treatment system, the controller having an adhesion amount estimation unit that estimates the amount of microorganisms adhering to the flat plate, and a rotation-speed-switching unit that causes the rotation speed of the flat plate per unit time to change on the basis of the result of estimation by the adhesion amount estimation unit.
